Wh...HI, Need some info on transaction per second. What it actually means, Transaction occuring in sql in the given interval. What is the meaning of transaction here? Is it the number of threads on which CPU is working OR number of fragments created by Cores and doing parallel processing OR Count of rows which it is processing or Data blocks or sizes which is being processed or page reads per sec or JObs/triggers working at the back picture.<br /><br />What all it considers in the TERM TRANSACTION. Can you please help me in this?Anonymoushttps://www.blogger.com/profile/04334005513870470770noreply@blogger.comtag:blogger.com,1999:blog-495177919198719500.post-88463616922021130342014-01-27T12:09:09.684-08:002014-01-27T12:09:09.684-08:00Transactions Per second:

As I understand it,...I'm a bit puzzled by this. As I understand it, you are getting the transactions per second from one database, waiting a second, and then and subtracting this from the transactions per second from another database. The MSDN description for the counter is 'Number of transactions started for the database per second.' so why would you need to calculate the difference in TPS between two different databases (or even the same one) after a second?Anonymousnoreply@blogger.com
